Python - update value of attributes

[bruniii]

Dear James,

first of all, thank you for this package and all the work required!

Using the python wrapper, I'm trying to read a sor file, update some of the fields, export again to a second sor file. For now, only simple string parameters in the object SupplierParametersBlock and GeneralParametersBlock.

import otdrs
sor = otdrs.parse_file('data/serravalle.sor')
sor.general_parameters.cable_id='Test01'

but for every attribute tested I'm getting the error:

AttributeError: attribute 'data' of 'otdrs.DataPointsAtScaleFactor' objects is not writable

Ideally, I would like to call your python module from LabVIEW to create from zero a .sor file (or, if needed, starting from a dummy .sor file and than update the relevant fields), using data acquired by the LabVIEW application. It's a convoluted way to make it but for now it's also the only one I can think about.

Since in the readme of the repo you wrote:

Editors are responsible for ensuring that any modification of data elsewhere in the file makes sense, e.g. if the number of points within a DataPointsAtScaleFactor struct is changed, then the n_points field must be amended by the editor; otdrs will not do this for you.

I expected to be able to at least change the parameters, if not the array of attenuation data. Am I wrong? Can you help me on this?

Thanks again,
Marco.
